Cartridge amplifier with remote input device

jcarr · 18th March 2003, 06:15 AM

Amplifier for a phono cartridge, with a remote input device integrated into the headshell / tonearm.

Commercialized by Yamaha, as the HA-2 and HA-3 phono stages.

Possibly a nice DIY project, especially if you are ok with SMD devices.

I was led to believe that in their early days Clearaudio marketed a headamp that went between cartridge and headshell.

Yup.
I recall that too, unfortunately I never heard it.

Cheers,
